(AMER CHEMICAL SOC, 2005-10-28)Photoreduction of oxoisoaporphine dyes occurs via a stepwise mechanism of electron-protonelectron transfer that leads to the N-hydrogen oxoisoaporphine anion. When triethylamine, TEA, was used as the electron donor in ...
-
(The American Society of Photobiology, 2013)Photoinduced electron transfer between N-phenylglycine (NPG) and electronically excited triplets of 7-substituted-3- methyl-quinoxalin-2-ones in acetonitrile generate the respective ion radical pair, where by decarboxylation ...
-
(Royal Society of Chemistry, 2019)New 4-amino-3-iminoquinoline derivative ligands (L1-4) were synthesized through an intramolecular exo-dig cyclization of anionic β-diketiminates, containing an N-benzonitrile moiety. The effect of the alkali-metal in this ...
-
(Wiley-Blackwell, 2015)To obtain mechanistic insights into the cross talk between lipolysis and autophagy, two key metabolic responses to starvation, we screened the autophagy-inducing potential of a panel of fatty acids in human cancer cells. ...

(American Chemical Society, 2013)An unusual and unique conformation of a paddle wheel type binuclear copper(II) complex containing acetate and acetamido ligands, {Cu2(μ2-O2CCH3)4}(OCNH2CH3) (1), was obtained by solvothermal synthesis. The structural ...
-
(Amer Chemical, 2020)A series of functionalized 6-alkoxy phenalenones was prepared through an unprecedented oxidative dealkylation of readily available phenalene precursors. The starting phenalenes were efficiently synthesized via an aminocatalyzed ...
-
(National Institute of Health, 1989)Almost every week, it seems, another character appears, expending the cast of DNA-binding proteins. Some of these proteins are destined for major roles, binding to DNA sequences a few hundred basepairs upstream of key ...
-
(2011)In this paper, the uptake of Cu(II) ions from an acidic aqueous solution using a continuous column packed with microcapsules containing the chelating extractant LIX-860 N-IC was examined. A simple, economical method was ...
-
(1980)Urease (EC 3.5.1.5) was purified from Spirulina maxima by ammonium sulfate precipitation, DEAE-cellulose chromatography and gel filtration on Sephadex G-200. The enzyme had maximum activity at pH 8.7, a Km for urea of 0.12 ...

(PROUS SCIENCE, SA, 1998-03)Acetazolamide is recommended for the prophylaxis of acute mountain sickness symptoms which sets in on climbing to high altitudes (H) above 2,500 m. It is primarily excreted unchanged in urine. In a previous study, we ...
-
(1986)An HPLC method described by Mancllla and Gll [Analytical Letters 17,(B9),1984,873-886] has been applied to study the sex dependent expression of several rat liver testosterone hydroxylases. A sample clean up procedure has ...
